In some embodiments, as shown in fig. 1 and 2, a method comprises:
step S10: a server of the system creates a project based on a project creating request of a user and generates a sharing link of the project;
in the embodiment, one of the users can log in the system by using an account, create a project to be collaboratively edited, generate a sharing link of the project and/or select at least one collaboratively edited user; the sharing link is used for being sent to other users, so that the other users can join in the project to be collaboratively edited, and the selected user can join in the project collaboratively edited after logging in the system. In other embodiments, the sharing link may also be used to directly link to the component model to be collaboratively edited, that is, the component model to be collaboratively edited may be opened by clicking the link.
Step S20: the server creates or opens a component model contained in the project based on a component creating or opening request of a user, and enters an editing state for the component model;
in this embodiment, any user who opens the component model can visually display the model, and any user can send an editing request to the server, that is, on the server, the component model is in an editing state, but specifically, which user can edit the component model, and further determination is needed.
Step S30: the server determines the number of users who have requested to edit the feature based on the ID information of the user and the feature ID information of the feature of the component model, and the following situations may occur:
step S40 a: if the same characteristic is edited by more than two users, the server automatically and dynamically locks the characteristic and gives the users meeting the set conditions the editing right, and the other users cannot edit the characteristic;
step S40 b: if the same feature is requested to be edited by a user within the range, the server automatically and dynamically unlocks the feature, and the user can edit the feature.
In the above embodiment, each user logs in the railway BIM system by using the account, the user side used by the user only plays a role in sending a request command and displaying, and the server is used for calculating and storing. The user side sends a request command to the server and simultaneously carries the ID information of the user side, and the server receives the command request and the carried ID information so as to judge and process.
In the above embodiment, the component model stored in the server includes a plurality of features, each feature includes feature ID information, and the server determines the number of users requesting to edit based on the identity ID information of the user requesting to edit a certain feature, thereby avoiding a conflict and an error when more than two users edit the same feature.
According to the multi-user collaborative editing method of the railway BIM system based on the web real-time modeling, the same component model can be edited, the cooperativity in the process of editing the component model is increased, and the method is suitable for multi-person heterogeneous collaborative processing of a database containing a large number of components.
In the above embodiments, a project to be collaboratively edited may be created by any one user, and the project described herein may be a member set. While creating the project, other user members can be selected to become users of the collaborative editing; links can also be generated and made users of collaborative editing by letting other users enter the way in which links actively join.
In the above embodiments, the component model refers to a three-dimensional model of a component in a railway BIM system, and the component is an integral part of the engineering subject, or is independent or combined with other parts to complete at least one main function of the engineering subject. The most widespread period of component use is early in the project to determine the physical, operational, and aesthetic characteristics of the project. The component is defined according to the functional characteristics, irrespective of its technical implementation, construction method and material composition. Such as a stone pad, pallet/tie-beam, pedestal, pier/column/platform, arch ring, cable tower, stay cable, etc.
The component model described herein is a solid model or a surface model, and may be composed of at least one feature. The solid model records not only all geometrical information but also all point, line, plane and volume information.
In the building process of the component model, a complex entity is constructed by utilizing the geometric element construction function and the relation operation function of the railway BIM system and performing operation on the simple entity sets from top to bottom to obtain intersection, union and difference. The geometric element structure function can also be called as a two-dimensional sketch, and mainly comprises the steps of drawing points, lines, surfaces and the like in a plane; the relational operation function may also be referred to as a command, for example, the command may be stretch, cut, rotate, array, and the like.
In the embodiment, the invention provides a multi-user collaborative editing method of a railway BIM system based on web real-time modeling, all calculation and storage of a BIM model are put on a server for processing and storing, a user side only plays a role in sending and displaying commands, the requirement for heavy BIM software calculation can be finished by any intelligent terminal in any place with a network, the requirement for any equipment to operate BIM software in any place and any time is met, and the problems of high performance requirement, high purchasing cost, complex installation and the like of the BIM modeling software of the traditional user side on a computer are solved.
In some embodiments, when multiple users edit the same feature of the same component, the server determines the number of users who enter the editing state for the feature of the component model at the same time; if the feature is edited by more than two users, the feature is automatically and dynamically locked by the server, the users meeting the set conditions have editing rights, and the other users cannot edit the feature. For example, the setting conditions may be set to a chronological order of entering the editing state or according to the authority level of the user.
In the above-described embodiment, the number of users who the server determines that the feature enters the edit state is determined based on the feature ID information that each feature has and the identity ID information of each user.
In an embodiment, the setting condition is based on a chronological order, and the server gives an editing right to a user who enters an editing state first. In the case where two or more users edit the same feature of the same component, the server gives the user who first enters the editing state the editing right. The user that has lagged behind the edit status can continue editing until the user that previously edited the feature exits the edit status.
In another embodiment, the setting condition is based on the authority levels of users, the server stores authority level information of each user, the server compares the authority levels of the users who edit the same feature of the same component at the same time, and the server gives the users with higher authority levels to edit.
Under the condition that more than two users edit the same feature of the same component, a command for editing the component model by operating the user side by the user carries identity ID information and is transmitted to the server; the server stores the authority levels of all the users, and the server gives the users with higher authority levels the editing right.
The embodiment of the invention discloses two priority editing right modes, which have better fairness according to the time sequence and are suitable for most scenes; according to the authority level of the user, the method has better practicability and is convenient for the user cooperative processing of designers in different levels.
For example, as shown in fig. 4, the component model is shown to be formed by combining two features, wherein the feature 1 is a cuboid, the feature 2 is a cylinder, and the feature 2 is established on the basis of the feature 1. Assuming that user 1 and user 2 edit feature 1 simultaneously, they can edit the rectangle length, width and position of the plan sketch, and can also edit the commanded stretch height.
Firstly, according to a time-sequence setting mode, the server automatically and dynamically locks the editing right of the characteristic, and if the user 1 firstly enters an editing state, the user 1 has the editing right; the user 2 enters the edit state, but cannot edit the feature 1, and this state may be referred to as a pseudo-edit state.
And secondly, according to the setting mode of the user authority, assuming that the user 1 and the user 2 enter an editing state, and the server automatically and dynamically locks the editing right of the characteristic. The server compares the authority levels of the user 1 and the user 2, the user 2 has higher authority registration, and the server gives the user 2 the editing right; although the user 1 enters the edit state, the feature 1 cannot be edited, and the state of the user 1 may be referred to as a pseudo-edit state.
In the above embodiment, two or more users edit the same feature of the same component, and the server sends a prompt to a user who cannot edit the feature. The prompt displayed at the user end can be a popup prompt, such as "temporarily unable to edit", "please later", etc.
In some embodiments, different users can edit different features of the same component model at the same time. The editing rights for the feature are automatically and dynamically locked by the server. For example, while user 1 is editing feature 1, user 2 may edit feature 2.
In some embodiments, after one user finishes editing a feature, the server displays the edited component model to other users. For example, the user terminal may have more than two display areas on the display screen at the same time to display the component models edited by other users.
In some embodiments, the user side has a manual lock command icon and a manual unlock command icon on the operation interface to prevent other users from editing and modifying arbitrarily after one feature is edited.
In some embodiments, the component models of the items are stored on a server, and the component models are transmitted over a network and displayed at each user end.
In some embodiments, the server may store records of feature edits made by various users, so as to query their edit history, and at a later stage, to ascertain which users the component model was edited and modified by.
In some embodiments, while creating a project, it may be set that the export authority of a component model is determined according to the user authority level, preventing anyone from exporting the component model.
In some embodiments, the building and collaborative processing of the component models in embodiments of the present invention may be implemented in a web-based railway BIM system without the need for separate collaborative editing software or plug-ins.
According to another aspect of the present invention, there is also provided a multi-user collaborative editing apparatus for a web-based real-time modeling railway BIM system, the apparatus comprising a processor and a memory, the memory having stored therein computer instructions, the processor being configured to execute the computer instructions stored in the memory, and the apparatus implementing the steps of any one of the above methods when the computer instructions are executed by the processor.
According to another aspect of the present invention, there is also provided a computer readable storage medium, having stored thereon a computer program, which when executed by a processor, performs the steps of any of the methods described above.
